I was able to find the missing dependency at
But now some of the <a:commandLink rerender="" are not working.
Is the issue the well-formed-ness of the pages? I am using XHTML and as far as I am aware they are all well formed.
Could this be something else? I find it strange I had to go hunt down this dependency. Is this technology currently not mature/ supported?
Checked this issue. Looks like all links works as expected. It mustn't be the question of well-formed-ness. Did it works fine under Tidy Filter?
Provide please some more info(pages, libraries versions). And check may be you have some validation/convesion errors while submit your form.
